Miniaturized linear magnetic position sensors for automotive applications

In this work, a linear position sensor with a Hall effect element for automotive applications is presented The work involves the design of device structure, finite element analysis (FEA) computer modeling of sensor performance, fabrication of sensor prototype, and prototype characterization. The significance of the work is that a low cost linear position sensor has been developed with high linearity for use in automobile control systems. The complete sensor system is designed for ease of manufacturing and the harsh automotive environments.
